HW TEST 9

Objective 1

1.Farenheit, Celsius, Kelvin
2.Thermal Engery = energy of heat
3. High Spefic heat can absorb thermal energy without change in temperature.
4. Because humans are hot blooded and it makes the cold ice cube melt.
5. How much heat an item puts out.

Objective 2

1. They measure it using the circle on the end which has mercury in it to measure it.
2. Celsius = Freezing at 0 degrees celseius, used all of the world
Farenheit = Freezes at 32 degrees farenheit= used in USA and 4 other countries
Kelvin = Freezes at 273 K - named for Lord Kelvin
3. 41 degrees farenheit
4. 460 degrees celsius
5. 50K

Objective 3

1. Conduction, Convection, and Radiation
2. Hot to Cold
3. Conductors let heat in and Insulaters let out air
4. Conductor because it would let air in.
5. Fire becasuse if you were near a stream and you were to pour water on it, it would get warmer.

Objective 4

1.Temperature Changing.
2. Solids, Liquids, and Gases
3.It would stay the same
4. Thermal Energy
5. So that it can get air inside it

Objective 5

1.Expanding gas.
2. Both use heat; one uses thermal energy and one doesn't
3. They use air.
4. Takes out hot air.
5. With my Coke machine, the compressor did not work because it was old and the line was cut. We have to get a new one to cool down

Homework #6

1. If volume goes up, so does pressure.

2. They move more faster.

3. Jacques Charles

4. Flew balloon for 2 hours. Then it landed in a small town, Neslas - la- valle.

5. Pressure of Moles.

Science HW #5

1. When Volume Goes Up, Pressure Goes Down.

2. For example when you go up from Asheville to Spartanburg every morning, your ears pop because you are on a higher elevation than Spartanburg. So, if you put a balloon in a car in Spartanburg, and drove to Asheville, more air would go into it.

3. Pressure x Volume = Constant

4. How you breath is why doctor's study this.

5. When Volume Goes Up, Pressure Goes Down. They depend on the formula. When they go down to the bottom of the ocean for example, the lower they go, the more air they must use.

Science Homework Part 3

Homework Part 3

1. Some types of energy are kinetic,potential, electrical, electromagnetic, thermal, and chemical.

2. A rolling bowling ball has kinetic energy.
3. A bowling ball sitting still has potential energy.
4. A type of energy that is reflected by electronicwaves.

5. The type of energy that move electrons one place to another is electrical energy. An example of something that we use with electrical energy would be a television, phone, or anything we plug into the wall.
